Thermogenin is absent from tissue other than brown fat, but nevertheless fatty acids can uncouple in these other tissues (for reviw, see [S]). We assumed [2,5] ...

Specific amino acids in the BAR domain allow homodimerization

Next, we analysed whether SNX33 is able to form heterodimers with other BAR domain-containing proteins, in particular with its homologues SNX9 and SNX18, but also with the more distantly related SNX1. As a positive control, SNX33 was used. All four proteins were transiently expressed as HA-tagged pr ...
